Liquid exposure in MacBook Pro

9 days ago, I spilled liquid mixture (mostly water and some fruity liquid with sugar) all over my Mac (2019 Pro 15") from the left of the Mac. I wanted to keep it shut down when the spill happened but I accidentally kept turning it on because I must have been pressing a key while trying to wipe down water, carrying it around and putting it upside-down ( I hate how this version mac boots when pressing any button on the keyboard!!). On the same day, with my friend's help, I opened up and got rid of any moisture inside where the board and battery are and also wiped out like 2 corrosions (left side of the board) with alcohol. Then, I had it upside-down for a week without using, and when I finally turned it on 2 days ago, I found out the two left type-c usb ports were not working (I also had water inside on the left side of the screen, but it evaporated quite a bit with leaving some dotted marks). So, I opened up to see if there were any more corrosions or if I could just replace the usb-c board, but found out the area below left usb-c board was smoked. Cleaned the area with alcohol again, and I just decided to use it without the left usb-c's.

So, everything seems to be working perfectly fine, except the battery is draining really fast on battery power, and I assume it's because of the short circuit on the board where it was burnt? If only a portion of the circuit is damaged like that, will it eventually cause the board to die?
